RV Generator

Our motor home has been sitting idle for most or almost all of the winter. I went out last week to take a look and make sure the cold hadn’t gotten to it and that there were no obvious problems. I started the generator to exercise it for a while, and get it used to running again. I sat there mesmerized by the quiet purring sound of the generator, when suddenly the steady purr was interrupted by a surging sound. I immediately turned the appliances off that I had on, and listened closely to the generators RPM’s increasing and decreasing. After a few seconds of the generator sputtering up and down it smoothed back out to a nice, steady purr again.
When I worked at an RV dealership, our service department was always booked with appointments for generators that either wouldn’t start, or if they did, they had that all too familiar surging sound. This was a result of letting the generator sit for periods of time without starting and exercising it. Lack of use is one of the biggest problems with generators and can severely damage your equipment. In gasoline generators the fuel breaks down and thickens causing hard starting and surging problems. This can happen in as short a period of time as one month.
